' ALEXANDER LATIMER, OF LONDOK, ENGLAND.

AUXILIARY RIM FOR VEHICLE-WHEELS.

Application filed October 22, 1909. Serial No. 524,010.

To all whom it may concern:

Be it known that I, ALEXANDER LATIMER, a subject of the King of Great Britain and Ireland, and a resident. of London, England, have invented certain new and useful Improvements in Auxiliary Rims for Vehicle- Wheels"; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to improvements in auxiliary pneumatic-tire-carrying rims adapted to be detachably secured to the wheels of motor car and other vehicles particularly those having removable flanges.

Hitherto, such detachable tire-carrying rims have been madeof a rigid formation, which renders difiicult the application and removal of the tire respectively thereto and therefrom.- Or such rims have been made of segments generally three two of which form an abutment joint which breaks the continuity of .the circle and a screw jack or I similar special mechanical appliance, hasto be used to dislocate the abutting parts to collapsethe rim or to expand the rim to locate the abutting parts. Further, special means have to be adopted 'to fit these discontinuous rims on the wheel and to restrain their radial expansion.

The present invention has for its object to construct a detachable tire-carrying rim which can be more readily applied and removed respectively to and from a tire as and when desired, and which possesses the advantage that no tool is required to perform such operations, and that no special means are required to secure the rim on the wheel, or to restrain its radial expansion.

To this end, the invention consists in forming the rim of a flexible nature radially and of a continuous and inextensible nature circumferentially, so that the rim can be collapsed and sprung into position upon the tire by hand, (much more easily than the tire could be forced over a rigid rim,) and.

- so that when in position upon the tire the rim can be secured in position on a wheel by means of a detachable flange or detachable flanges or in any other customary or suitable manner.-

The invention is shown in the accompanying drawings, in which Figure 1 represents a side view of a pneumatic tire fittedv witha flexible continuous and inextensible -tirecarrying The rim is shown in full lines with part extending around and engaging the'bead otthe lower part of the tire and with part bent inward away from the tire. The dotted lines represent the bent-in portion engaged with the bead of the upper part of the tire.

- Fig; 2 represents a section on line 22, Fig.

1.. Figs. 3 and t illustrate diagrammatically the method of applying and removing the r m to and from the tire. Fig. 5'is a similar Specification of-Letters Patent. Patented NOV. 21, 1911. v

view to Fig. 2, showing the tire carrying' rim applled, by way of example, to a wheel fitted with a known ,form of removable flange. Fig. 6 represents, by way of example, how the rim may be applied to a wheel telly not having flanges. Fig. 7 represents a section on line 9-9, Fig. .6, but not showing the tire.

In carrying out the invention, the improved tire-carrying rim is constructed of a series or plurality of sections or segments, a, shaped channel-like or otherwise in cross section according to the'tire to" be carried thereby and to the form of wheel or wheelrim the'tire-carrying rim is intended to be used with, and arranged and connected L0- gether end to end in annular and continu- ,ous form. v

The sections or segments are or may be fastened by rivets b, or in other suitable manner, to one or more flexible and inextensible retaining bands or rings, a, of

spring steel as shown. The bands or rings are made continuous without a joint or have their ends meeting and connected together in any suitable manner preferably by being riveted over one another so as to form a lap-joint, as shown at 0 It will be noted that the sections or segments are made of short lengths and have their ends inclined or chamfered oil so as to leave V-shaped spaces, m, between adjacent sections or segments to permit of the rim being bent radially inward as indicated, by wayof example, in Fig. l, in applying The bands or rings exercise a restraining action upon the sections or segments and prevent the expansion of the tire when in-' flated from displacing'the sections or 'seg ments, and allow of the free inward radial movement of the sections or segments during the operations of fitting and removing the tire on and from the rim, the operator being able to readily efi'ect said inward acand removing the same to and from the tire i tion by hand, and the inhei'ent springy nature of the rim facilitating saidopera- .1, 2, Fig. 3, whereupon the rim can be moved radially outward or inward as indicated by the arrows, 3, 4:, Fig. 3, to apply or remove the same.

Fig. l represents the rim and the tire in the operation of applying or removing the former to or from the latter.

lngFig. 5, d, represents a wheel felly fittedwith a known form of fixed flange, e, and removable flange, e and the form of construction of the tire carrying rim represented in Fi s. 1 and .2, is shown as applied thereto in the customary manner of a rigid endless detachable tire-carrying rim. In Fi 6 the tire-carrying rim is shown as applled to a wheel felly not having flanges, but havinga plain fixed metal rim," e Inthis case the sections or segments, a are provided on their inner peripheral faces with blocks or distance pieces, a A sufiicient number of these are provided with trans'verseholes, a through which pass spindles, a having at their ends, stops,

arms or levers, a, a, which are preferably rounded on their inner sides to obtain a wedging action and which may be turnedradially so as to engage the sides of the wheel felly and hold thetire -carrying rim from lateral displacement, or may be turned tangentially so as not to engage the sides of the wheel felly to permit application or removal of the tire-carrying rim.

The levers are secured in their radial position preferably by bolts or the like, (1 engaging the wheel felly and thus also aid in preventing creeping. The wheel rim, 6 may also be provided with a fixed stop or stops, (2?, for this purpose.

The blocks are slightly inclined on their inner faces, a, to facilitate the appli ation of the tire-carrying rim to the wheel-rim, 6 which may also be complementarily shaped on its outer face.

What I claim as my invention and desire to secure by Letters Patent is An auxiliary tire-carrying rim consisting of a plurality of sections or segments shaped channel-like in cross section and having their :ends inclined or chamfered oil",

a continuous flexible resilient and inextennesses.
